Upgrades

An upgrade scenario from an earlier installation into Enterprise Server v3 Prelude is
not supported. The command-line interface and configuration are compatible.

application-root Attribute in
the domain.xml File

You should not modify the default setting in the domain.xml file
for the application-root attribute.

The domain element's application-root attribute In
the domain.xml file is intended to specify where the
server will expand application archives when the user deploys them.

Currently, not all places in Enterprise Server v3 Prelude that should use
this attribute do so. Some uses of the attribute assume that applications
are to be expanded in ${com.sun.aas.instanceRoot}/applications.

Unsupported Options in asadmin Commands

The help for asadmin commands describes some options
that are not supported by Sun GlassFish Enterprise Server v3 Prelude. For example:

Options that relate to clusters and multiple server instances,
for example, the --target option

Options that relate to profiles, for example, the --profile option

If you specify an unsupported option, a syntax error does not occur.
Instead, the command runs successfully, and the unsupported option is silently
ignored.

Multi-Mode Operation

Examples in the help for asadmin commands show the
commands in multi-mode operation. Multi-mode operation is not supported by Sun GlassFish Enterprise Server v3 Prelude.
All asadmin commands must be typed separately on the operating
system command line.
